      Hey #infosec community, etymologically speaking, do you consider silent patched bugs as 1-days or 0-days ? Cc @maddiestonehttps://twitter.com/maddiestone/status/1197590661794414593 …

      I have gone back & forth on this bug. In some ways it's a 0-day, in other ways it's a 677-day. In it's impact, it's a 0-day: there are no patches available to users & weren't any patches planned because while it was a reported "bug", it was not assessed to be a security bug. 1/

      Replying to @maddiestone @Pat_Ventuzelo

      There were no detections in place for the presence of the bug nor was anyone looking for exploitation...like a 0day. OTOH, it was reported & patched upstream 677 days prior. Attackers could have found the bug by combing patches, like an n-day. So my soln was to call it neither

      FWIW there is a thorough discussion of terms (some new) that describe the "life status" of a bug in "Zero Days and Thousands of Nights" by @LilyAblon (starts on page 28)https://www.rand.org/pubs/research_reports/RR1751.html …
